Korg microX (2007)

A 25-key synthesizer and USB MIDI controller with HI synthesis and 640 onboard programs

Overview

The Korg microX is a compact synthesizer and USB MIDI controller released in 2007. It has 25 full-size keys and comes with a dedicated plastic case. It runs on Korg's HI (Hyper Integrated) Synthesis system with 64MB of PCM waveforms, and it carries 640 factory programs and 384 combinations. Korg positioned it as a scaled-down version of the Korg X50. It shares half its sounds with the Korg TR series, adds new presets, and keeps the X50's software integration.

Design

The microX uses Korg's HI Synthesis engine and works as a USB MIDI controller. It connects over USB for MIDI control. It was described as a "compact X50," with half the sound set of the Korg TR, new presets, and the software-controllable features of the X50.

Context

Released in 2007, the microX was aimed at musicians who wanted a portable, affordable synthesizer with professional sound. It sat between budget controllers and full workstations, with built-in sounds and USB integration. It was marketed alongside the larger X50 and aimed at mobile performers and producers, who got the included carrying case and a streamlined feature set.

Market

A used microX was listed for $299 in 2008, shortly after release. In recent listings, the best prices start at $240. No common failures or maintenance issues were reported in available sources.
